Title: Tracking device
Inventor: SAITO OSAMU
IPC: G01S13/72
Filed: 1990-06-06
Abstract: PURPOSE:To reduce a decrease in antenna gain and to shorten a detection distance by correcting the steering signal so that the relative position relation between a target and a guidance device is looking down when head-on and looking when it is tail-chase. CONSTITUTION:A head-on and tail-chase decision device 16 compares the speed VMT of the tracking device M in the direction to the target 1 which is extracted by a relative speed detector 15 with the relative speed Vc between the target 1 and device M, and decides the head-on(HO) state when VMT < Vc and the tail-chase (TC) state when VMT > Vc. A steering signal correction part 17 corrects a height-directional correction signal positively in the HO state to set the device M above the target 1 and negatively in the TC state to set the device M is below the target 1, thereby steering the device. Consequently, a beam direction angle thetaA becomes wide under the influence of an angle alpha and the control is performed with the relative position relation wherein the antenna gain in the target direction does not decrease until right before movement to terminal guidance; and the device can be steered so that the direction angle thetaA becomes zero when the detection distance is reached, so the shortening of the detection distance is reducible.

Title: Evacuating device
Inventor: WAKABAYASHI MITSUO
IPC: C23C16/44
Filed: 1991-06-20
Abstract: PURPOSE:To prevent a vacuum pump from being damaged by a reactive gas in a sucked gas by fixing a heater to the body contg. the moving blade of a vacuum pump to be used in the evacuating system in the CVD device, etc., and a cooler to a motor. CONSTITUTION:A small amt. of an unreacted reactive gas still remains when the remaining reactive gas is removed from the waste gas derived from a CVD device through a vacuum trap and then discharged by a vacuum pump, and the remaining gas is brought into contact with air in the pump and hydrolyzed by the moisture in the air to form a fine powder which deposits on the inner wall of the pump. When the deposit increases in amt., the resistance to the rotation of the moving blade of the pump is augmented, and finally the moving blade is not rotated. Accordingly, a heater is provided to the body 2 contg. the moving blade to heat the body, hence the relative temp. in the body is lowered, the hydrolysis of the unreacted gas is prevented, and a motor 1 is cooled by a cooling pipeline 9. Consequently, the body 2 of the pump is not stopped by the accumulation of the deposit due to the hydrolysis of the remaining reactive gas, and the pump is operated over a long period.

Abstract: PURPOSE:To stabilize characteristics of a semiconductor device and to shorten the manufacturing process thereof, by implanting dopant ions in at least two oblique directions while using a gate electrode as an implantation mask for forming two different types of doped regions having different dopant concentrations, each at two places in minimum. CONSTITUTION:A field oxide film 2 for isolating elements is formed near the surface of a semiconductor substrate 1. Then a gate oxide film 3 is formed and a gate electrode 4 is formed thereon. By using the gate electrode 4 as an implantation mask, dopant ions are implanted obliquely in at least two different directions so that two different types of doped regions 7 and 8 having different dopant concentrations are formed by at least two for each type. For example, the dopant ions are implanted obliquely from one side and then the dopant ions are further implanted obliquely from the opposite side, whereby low concentration doped regions 7 and high concentration doped regions 8 are formed. The photoresist 5 is then removed and, by diffusion, the low concentration doped region 7 is converted to a low concentration dopant diffused region 9 and the high concentration doped region 8 is converted to a high concentration dopant diffused region 10.

Title: Intake control device for internal combustion engine
Inventor: HARADA ATSUSHI
IPC: F02D41/04
Filed: 1995-06-14
Abstract: PURPOSE: To prevent a reduction in controllability of intake at cold starting to prevent a trouble caused by this reduction in an intake control device for internal engine having an intake control valve. CONSTITUTION: An intake control valve 16 is provided between a surge tank 9 and an injector 4 within the intake passage 2 of an engine 1 in such a manner as to be openable and closable by an actuator 17. An electronic control device (ECU) 41 controls the actuator 17 in such a manner that the opening of the intake control valve 16 is held and fixed in a specified opening until the cooling water temperature reaches a prescribed temperature after the engine 1 is started. Therefore, even when the intake control valve 16 is slightly fixed by the icing of the moisture in the periphery of the intake control valve 16 in a case such that the engine 1 is started in extremely cold state, the opening an closing of the intake control valve 16 is never controlled.  Thus, the reduction in control precision is suppressed, and a trouble caused by that the intake control valve 15 is not precisely opened and closed is prevented.
